Newly identified cell population key to immune response
Date:3/6/2011

n the gut causes the immune response to go into overdrive and attack the body's own cells," he said. "A lack of the factor that is needed to generate active T-reg cells has also been implicated in human genome-wide studies of Crohn's disease. So it would seem that this cell population is strongly linked to the development of autoimmunity."

Dr Cretney said that re-defining the active subset of the T-reg population would give researchers the ability to develop new ways to increase or block their activity in the body. "The next step for my research is to look at the function of this active T-reg population in autoimmunity and in cancer."

Dr Kallies said that for these reasons, there was a lot of excitement in the medical community about regulatory T cells. "Clinicians have shown that regulatory T cell activity impacts on many therapies," he said. "Many research teams are trying to manipulate and expand these cells for therapeutic use. Our finding will transform the way that researchers look at immune responses and open new avenues for treating diseases such as autoimmunity and cancer."
